Kev nkag siab txog cov ntsiab lus tseem ceeb thiab kev ua haujlwm sib txawv ntawm cov khoom tshiab thiab qub yog qhov tseem ceeb thaum xaiv cov yob yob. Kev sib piv hauv qab no qhia txog ntau yam tseem ceeb: Hais txog hardness, cov khoom tshiab siv cov cuab yeej ua haujlwm siab dua, txhim kho hardness thiab hnav tsis kam. Nws Rockwell hardness ncav cuag HRA89-92, thaum cov khoom qub feem ntau muaj HRA87-90. Thaum lub sij hawm mus sij hawm ntev dov, cov khoom tshiab tuav ib tug smoother nto thiab txo hnav. Hais txog lub zog, cov khoom tshiab optimizes alloy muaj pes tsawg leeg, txhim kho nws lub zog dabtsi yog khoov thiab ua kom nws tiv taus ntau dua dov siab.
Cov khoom qub muaj lub zog khoov me ntsis qis dua thiab yooj yim dua rau kev tawg nyob rau hauv siab -load dov. Nyob rau hauv cov nqe lus ntawm toughness, cov khoom tshiab nta txhim kho microstructure, ho txhim kho toughness thiab muab superior cuam tshuam tsis kam piv rau cov khoom qub, txo qhov kev pheej hmoo ntawm breakage thaum dov. Hais txog dov precision, kev nce qib hauv kev tswj xyuas cov cuab yeej ua tau zoo dua qhov ntsuas qhov tseeb hauv cov khoom tshiab, suav nrog cov kab nruab nrab sab hauv thiab sab nraud, ua tau raws li qhov xav tau ntau dua dov precision. Zuag qhia tag nrho, cov khoom tshiab qhia tau hais tias muaj txiaj ntsig zoo hauv hardness, lub zog, toughness, thiab dov precision. Thaum xaiv cov khoom, yog tias cov kev xav tau ntawm dov tsis siab, cov khoom qub tuaj yeem ua tau raws li cov kev xav tau yooj yim; Txawm li cas los xij, rau siab -precision, siab-load dov, cov khoom tshiab yog qhov kev xaiv zoo dua.
